Title:
SCROLL-TYPE DISPLAY PANEL AND SCROLL-TYPE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/238930
Kind Code:
A1
Abstract:
A scroll-type display panel and a scroll-type display device. The scroll-type display panel comprises a display module (2); the display module (2) comprises: a support layer (21) and an array substrate (24); the support layer (21) comprises a first curled portion (211) and a second curled portion (212) which are distributed in a curling direction; the array substrate (24) is located on one side of the support layer (21), and an orthographic projection of the array substrate (24) on the support layer (21) is located on the first curled portion (211), wherein hollowed-out openings (41, 42) are provided on both the first curled portion (211) and the second curled portion (212), and the area ratio of the hollowed-out openings (41, 42) to the first curled portion (211) is greater than the area ratio of the hollowed-out openings to the second curled portion (212). On the one hand, the second curled portion (212) of the scroll-type display panel can withstand a large pulling force, thereby preventing the second curled portion (212) from breaking when the display module (2) is extended or curled; and on the other hand, the first curled portion (211) of the scroll-type display panel has a strong bending capability, so that a shearing stress generated by the layer staggering between the support layer (21) and the array substrate (24) can be reduced.
